Parlay architecture
Today’s service, switching, and transport networks are vertically integrated or intertwined that is, operators
generally have separate telephone, data, and broadcast networks. By contrast, the next generation networks will
employ a common switching and transport layer as connectivity network. This shows a need for a transition from
a vertically integrated network to a horizontal network, where transport and switching functions can be shared by
numerous service providers
For such a horizontal network, an open technology independent service interface is needed. The Parlay Group
thought the Parlay/OSA with that aim. It provides an additional layer of abstraction for the application developers,
and enables telecom operators and service providers to offer the same services to all existing underlying
networks: fixed networks, IP networks, and all mobile standards without having to adapt applications to network
specific protocols.
